18. Wildcard¶
Experimenting with Etched Glass was done during this week. A FabAcademy memorabilia!
The process 1) produce a vectorized image 2) cut the image on a vinyl material and place the material on the glass 4) sandblast the glass.
Vector Image¶
Roland CutStudio Software was used for producing a vector image and cutting/printing.

Final Outcome
Conclusion¶
Operating the machine was straight forward, probably the easiest in FabLab Oulu. There were few things that needed to be taken into consideration: 1) it is hard to see what is happening through the glass, even with the light was on; the process had to be stopped and the machine was turned off to check on the glass 2) The optimal angle is to face the target vertically (90 degrees) and make sure there is not blasting happening to the edges under the sticker (this would destroy the sticker by peeling it off) … In the end, all was well and nice result was obtained.
